Application filed August 29, 1908. Serial No. 50,819.

To'all whom it may concern:

Be it known that .l, AnoLF BELER, a citizen of the United States,residing at Pittsburg, in the county of-Alleghenyand State ofPennsylvania, have invented a new and useful Temperature-Regulator, ofwhich tho.

following is a specification.

Tlus invention relates to fluid. pressure regulators and has for itsprincipal object to provide a regulator of-extremely sensitive natu-reinwhich the controlling valve is opened and closed by the operation of anexpansible fluid exposed to varying temperatures.

A further object of the invention is to provide a thermostaticallyoperating pressure regulator in which the valve is under the control ofa confined body of expansible fluid.

A still further object of the invention is to provide a thermostaticelement in the form of a container havin an expansible portion thatquickly responds to variations in temperature.

With these and other objects in view, as

will more fully hereinafter appear, the invention consists in certainnovel features of construction and arrangement of )arts, hereinafterfully described, illustrate in the accompanying drawings, andparticularly pointed out in the appended claim, it being understood thatvarious changes in the form, proportions, size and minor details of thestructure may be made without departing from the s irit or sacrificingany of the advantages o the invention.

In the accom anying drawings :Figure 1 is a sectional e evation of afluid pressure regulator constructed in accordance with the invention;Fig. 2 is a detail View of a portion of the expansion chamber inexpanded position.

Similar numerals of reference are employed to indicate correspondingparts throughout the several figures of the drawings.

Co'u led to the flow pipe of the fluidto be contro led is a valve casinghaving a valve seat 11 that is arranged for the reception of a valve 12.This valve is normally held away from the seat by a helical compressionspring 13, the outer end of which exte nds into an openingformed in athreaded boss 14 on the valve casing. The outer end of the spring bearsagainst-a block 15 that is screwed within the o ening in order to permitadjustment of t e stress of the spring, and fit- Specification ofLetters Patent.

' dirt and prevent leakage. The valve casing is extended in cylindricalform to a bolting i flange 17 to which is secured the flange 18 of i anexternally threaded block 19 on which is 1 screwed the end of acylindrical casing 20. i The casing 20 is'closed at the outer end and isprovided with nip les 21 and 22 to which may be coupled the inlet'andoutlet pipes of a fluid circulating'system of any type.

I Secured to or formed integral with the block 19 is a tubular casing 23which communicates with a central passage 24 formed in the block. Theouter end of the casing is closed by a removable block 25, and saidcasing is tilled with some fluid that is-quickly responsive tovariations in temperature, such for instance as ether alcohol or mercurwhich are carried by collars that are screwed onto short couplingslocvos 31 the cndmost disks 33 and 34 of the expansion chamber beingprovided with flanges that are bent around the bossl27 and the valve 1;res pectivcly. When thcexpansion chamber is contracted the disks 29 comeclose together as shown in Fig. 1, and when expanded they spreadslightly as shown in Fig. 2, for the purpose of forcing the valve to itsseat.

In operation, the controlling fluid enters the casing 20 at the nipple21 and after circulating around the chamber 23 escapes at the nipple 22.The wall of the chamber 23 is very thin so that the temperature of thecontrolling fluid is quickly communicated to the expansible fluid insaid chamber 24. If the temperature of this fluid is higher than normalit will expand and force the chamber 28 to expand so that the valve 12will be forced against its seat or will be moved in the direction of itsseat a distance corresponding to the degree of temperature beyond thenormaliso that the flow of the controlling fluid throughthe valve-1Owill be diminished or altogether cut off. As the temperature of thecontrolling fluid decreases the cxpansible fluid will contract and thespring 13 will then force the valve farther away from itsseat.

What is claimed is valve casing havin a cylindrical extensionterminating in a ho ting flange and provided ries of connected disks 29,the inner ends of In apparatus of the class described, a

' 5 adjustable bearing block engaging the interior threads of the boss,a spring having one end thereof bearing against the valve-seat and itsopposite end engaging a bearing block, a threaded block having a flange10 bolted to the flange of the valve casing and provided with a centralopening, an expanslble chamber connecting the valve to the block andcommunicating with the opening,

a thin-Walled chamber extendin from the block and communicating with t eopening therein, said chamber being filled with an expansible fluid, anda fluid circulating casing mounted on the threaded block andsurroundinsaid thin-Walled chamber.

11 testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.
